    Specification. A.D. 1858.—N° 1083. 3 Jones Apparatus for Draining and Collecting Sewage, <§c. fall into the cistern to be removed therwith. In the event of the water beimr o inconveniently high, a small hand pump conveniently fixed to the side will reduce the water to a proper level, & any liquid sewage which may stand above the cistern, which can be effected (so soon as the flood-gates are down), 5 and the same made to pass away through a small hole in one of theis gates with a door to it. The flood-gate that arrest the water in its course should be tolerably water-tite, the others would not be so particular in their fittings. Upon reopening the flood-gate, an important object will be gained by the rush of water from that part, clensing the Sewer of any stopage or acumulations, 10 and prevent danger from explosive gasses by creating a circulation, and causing fresh air to rush in. Figure 4 of letter B showes a front elevation & section of the grate 4, fixed at the wide mouth of the sewer. The horizontal section of which shows also the improved socket bricks, and the structure of the sewer with them. 15 Fig. 8, 8, are loose plates made to rest upon the edge of the cistern, to shut out the descending water & debris from the space between the cistern & the wall surrounding it, and thus prevent trouble to the men in its removal. Fig. 9 is a horizontal section of the man-hole, showing the grooves in which the plates or flood-gates are guided up & down. When not in use they will 20 be suspended from the frame of door surrounding the man-hole, which frame is on a level with the pavement. Fig. 10 is a new form of trap for a watercloset; a, a, coloured red, are expanding joints made of gutta percha or other suitable elastic material; b, b, is a leaver, the handle of which, when pulled upwards, causes a depression 25 of the pipe constituting the trap, from the line c of water level in the pan to d, by which the contents are emptied into the sewer, the leaver also being attached to the valve of the cistern will admit a fresh supply of water to the pan. Fig. 11 is the trap in its detached form, as made by the manufacturer, with 30 collars or projecting fillets, or beads, for securing the expanding joints more firmly to the pan, and the descending pip communicating with the sewer, the dotted line at e showing the lower end of the pan /. The socket pipe q must be so set as to allow the trap to work freely from the center joint h9 which joint or hinge may be formed with the trap & pan, or of the elastic matereal 35 forming the expanding joint, or of iron, with a band around the trap and pan. Letters C & D is an improved machine for making the blocks or bricks to be used in the construction of the sewers, by the use of which they will be more imperveous against sewage water & noxious gasses. A is the pug mill, with knives for grinding the clay, and an archimedian
